Need help ID'ing

Acquired this in the past week, daughter wanted it. Suspect it is possibly a pre-1950 artillery shell of some type but don't know much more than that about it, just the shell, no internal components at all. Measures 5" in diameter, 14&3/4" tall and weighs 16.5 pounds - anyone know what it possibly is, what fired it?

Markings on the bottom?

Looks like a naval AA shell. I believe the "HC" refers to "High Capacity" (bursting charge)

No markings on the bottom.

Possible anti-aircraft?

Cross posted for ya. Thought the old timers at AO might have some clues.

I think it's an instructional round for a 5" dual purpose WW2 era naval deck gun (dual purpose like the AA/AT German 88, except this one would be AA and Land), American made (hence the American looking munitions factory stamp) but widely manufactured and used by almost all western Allies during and after WW2, whoever needed them.

ADF I'll bet to be Australian Defence Force. You could have combined fitted powder case and projectile rounds (like a bullet), or separate powder case then projectile like this one you have in front of the case if you needed to set different fuse times. The Mark 44 doesn't line up with any large guns of the era so I think it's an indigenous nomenclature for that particular gun.

Holy shit, so this is actually a stabilized rocket warhead. MK 44 is the centrifugally armed fuze it uses :nut: I was totally wrong, gj Tezzating


The Zuni MK7 unguided rocket (https://en.wikipedia.org/wiki/Zuni_(rocket)), used in the American-Vietnamese War, still in use today but now packed with laser guidance equipment, crazy:


The Zuni is a 5.0 in (127.0 mm) unguided rocket deployed by the United States armed forces.[1] The rocket was developed for both air-to-air and air-to-ground operations. It can be used to carry various types of warheads, including chaff for countermeasures. It is usually fired from the LAU-10 rocket pod holding four rockets.

The Zuni 5-inch Folding-Fin Aircraft Rocket (FFAR), was designed as a modular system, to allow the use of different types of warheads and fuzes. One type of warhead was a proximity fuze, as the rocket was originally intended to be used as an air-to-air rocket. The Zuni was approved for production in 1957. A number of different launchers were tested for the Zuni, e.g. single launchers fitted to the AIM-9 Sidewinder launching rails of the Vought F-8 Crusader. However, four-tube LAU-10/A series pods became the most commonly used launcher.
